I've posted this before but the problem is continuing. I thought it might be the plywood panel over the spare tire which did make a noise when I flexed it, but after stuffing a couple of old undershirts under it, the panel did not move but the loud clunk continued when I drove the car over a rough road. Here are the facts:
1. The noise only comes when driving over a rough road - including my driveway. It is not dependent on speed.
2. It is very loud. Sounds like a sharp "Clunk".
3. Unlike when I had a bent tube shock rod, bouncing the rear bumper up and down makes no noise at all. (Note - as I've posted, suspension travel is limited). The bent rod made a clunk every time the suspension moved up and down - not as loud - more of a loud click.
4. The shock bolts are tight.
5. Usual small TR6 clunk when letting out the clutch or backing up. Last time we checked, the diff mounts were fine. They had been weld reinforced when I bought the car.
6. Right trailing arm bushings were replaced when we put a new arm on there and hub was rebuilt by TRF.
7. Stainless steel exhaust system seems tight with all hangers in place. Single pipe system.
I will award a prize to the expert out there who can correctly diagnose the problem and tell me what must be done.
